Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an engine start key switch actuator used when remotely starting an engine of a vehicle.

[0002]

[Prior art]

 Conventionally, in a vehicle experiment, there is an engine start key switch actuator used when the vehicle is placed in a laboratory and the engine is started and stopped by remote control.

As a conventional engine start key switch actuator, there is, for example, one shown in FIGS. 4 to 5 (see Japanese Utility Model Laid-Open No. 61-155573).

That is, the key switch (ignition key) 101 inserted in the key hole 107 is held by the holder 102. Further, a driving source 105 for rotationally driving the key switch 101 is fixed to a fixing jig 104 fixed to the seat back 103. Then, the holder 102 and the drive source 105 were connected by a flexible cable 106.

[0005]

[Problems to be solved by the device]

 However, in such a conventional engine start key switch actuator, since the drive source 105 is present on the fixing jig 104 side and the holder 102 side of the key switch 101 is connected by the flexible cable 106, When the rotation axis of the drive source 105 is largely tilted with respect to the rotation axis of the key switch 101 or is installed in a state where the rotation axis is greatly deviated, the flexible cable 106 is twisted, or the driving force transmitted to the key switch 101 varies greatly. There was a problem to do. Therefore, when returning the key switch 101 from the start position to the ON position, there is a problem that it cannot be returned only by the return spring.

The present invention has been made in view of such conventional problems, and can smoothly transmit the driving force from the driving source to the key switch, and can be mounted on the vehicle. The purpose is to provide an engine start key switch actuator that has a high degree of freedom in site selection.

[0007]

[Means for Solving the Problems]

 Therefore, according to the present invention, the key switch holder for holding the key switch, the drive source that is integrally connected to the key switch holder, and rotationally drives the key switch, can be engaged at a predetermined place around the driver's seat of the vehicle. And a flexible member that connects the fixing jig and the drive source and has a bendable flexible member that has sufficient torsional rigidity against a key switch rotation drive reaction force of the drive source.

[0008]

[Action]

 Since the key switch holder and the driving source are integrally connected, the driving force is directly transmitted to the key switch.

Further, since the flexible member is bendable, it does not twist due to the reaction force of the driving force, so that the flexibility of selecting the mounting location of the fixing jig is great.

[0010]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 and 2 are views showing an embodiment of the present invention.

First, the configuration will be described with reference to FIG. Reference numeral 1 is a key switch (ignition key), 2 is a key switch holder for holding the key switch 1, and the key switch 1 is fixed to a key switch holder 2 by a fixing bolt 3. Reference numeral 4 is a speed reducer, and 5 is a drive motor that is a drive source for rotationally driving the key switch 1. The drive motor 5 is integrally connected to the key switch holder 2 via a speed reducer 4. 6 is a flexible member having a sufficient torsional rigidity, which is fixed to a fixing jig 8 by a lock bolt 7. The fixing jig 8 is used to fix the engine start key switch actuator at an appropriate position on the vehicle, and is fixed to the steering ring handle 10 by a fixing nut 9 in this embodiment.

The key switch 1 is inserted into the key switch hole 11 on the vehicle side shown in FIG. 2 at the time of an experiment.

Next, the operation will be described. The engine start key switch actuator has one end fixed to the steering handle 10 by the fixing jig 8 and the other end held by the key switch holder 2 holding the key switch 1 inserted in the key switch hole 11 shown in FIG. It is in.

To start the engine, a signal is sent to the drive motor 5 from a control circuit (not shown) through the connector 16 to drive the key switch 1 to rotate clockwise to the START position in FIG. Wait until the engine speed exceeds the set value. Stop the drive when the engine speed exceeds the set value. The key switch 1 is returned to the ON position by a return spring (not shown).

The engine is stopped by driving the key switch 1 to rotate counterclockwise and waiting for a fixed time or until the engine speed becomes zero.

According to the present embodiment, since there is no flexible cable between the drive motor and the key switch holder as in the conventional case, the drive motor 5 and the key switch holder 2 are integrally connected, so that the drive Since there is no change in force and there is no need to perform feedback control of the drive motor 5, key position teaching is unnecessary and the control circuit becomes simple.

Further, the key switch 1 may be controlled to three positions of OFF, ON, and START. If the drive is stopped from the START position to the ON position, the return spring returns the drive motor, which is a drive source, to the right rotation, There is often no need for special functions or controls as long as there is a state of left rotation and free rotation.

Furthermore, the key switch holder 2 and the drive motor 5 are integrally connected via the speed reducer 4, and the drive motor 5 and the fixing jig 8 are bendable and have sufficient torsional rigidity. Since they are connected by the member 6, the degree of freedom in selecting the mounting position of the vehicle fixing jig 8 is great.

FIG. 3 shows another embodiment of the present invention. In this embodiment, an air type rotary actuator 12 is used as a drive source instead of an electric motor. Further, in the present embodiment, the engine start key switch actuator is fixed to the door 15 by the fixing nut 14 of the fixing jig 13.

According to this embodiment, the same effect as that of the above embodiment can be obtained, and further, since the control circuit of the speed reducer 4 and the drive motor 5 of the above embodiment is not required, the structure is simplified. . However, it is necessary to select an air rotary actuator 12 which has a small friction when rotating.

[0021]

[Effect of device]

 With the configuration as described above, according to the present invention, it is possible to smoothly transmit the driving force from the driving source to the key switch. Further, there is an effect that the degree of freedom in selecting a mounting location on the vehicle is increased.
